Quote from Peter;1178423:
Do we have a say in things we'd like to see in Mabi NA or is all of Mabi NA's content strictly from overseas?
Not all content from NA mabi is strictly overseas, such as our rewards system for both the saga, and the existence of the adventure seal shop and adventure seals (and some daily quests). There are some things that are different in NA than other servers or they don't have it at all, but not many.
There has been two cases where Kenero posted a petition on the nexon forums and they gave in and released it, but we don't know if the petition actually helped or it was a coincidence because they were going to release it anyways. Although now, petitions are no longer allowed on the nexon forums.
You COULD send a ticket under suggestion to Nexon, but I have little to no hope that will ever reach Korea (because Korea has to make stuff for all servers, including exclusives).
The Korean test team does hold a suggestion thread every few months, where you could write up to three detailed ideas, and in the end we narrow it down to what we consider the ten best ideas and put a suggestion ticket under KOREAN Nexon, though we only had one so far and none are currently running. It's a nice idea, not everyone can access a Korean Nexon Account so it's nice to give NA Mabinogi players a chance to have their ideas heard.
